Nanotechnology is a rapidly developing science and a number of methods are now available for producing nanoparticles. However, some of these methods employ high energy requirements, low material conversions and the use of hazardous chemicals. Hence, there is a growing need to develop eco-friendly nanoparticle synthesis methods.

Nanowires have a number of exciting properties which are not exhibited by 3-D or bulk materials. This is due to the fact that electrons within the nanowires are quantum confined and have energy levels that differ from that of the bulk materials.
In the near future, it is very likely that hospital patients will no longer have to be hooked up to wires and monitors thanks to the emergence of temporary electronic tattoos which can be used to monitor the vital signs of a patient.

Graphene has been the focal point for many research projects in recent years. It has proved to be one the most diverse materials known to man and recently a team of researchers from Northwestern Engineering have stumbled upon a method of creating graphene ink while trying to discover a new method producing graphene.

Atomic force microscopy (AFM) is a non-destructive and non-intrusive imaging technique used to visualise the intricate structure of microorganisms such as viruses at extraordinarily high resolutions. Using AFM, researchers can identify and study membranes, RNA and DNA, and protein assemblies and their substructures.

Graphene has offered scientists and engineers new possibilities for optical, electronic, and mechanical materials. There are widespread graphene research activities happening across the globe since it was discovered in 2004. Now, researchers from the National University of Singapore (NUS) have found a way to grow and transfer graphene with very few defects.

Since its discovery in 2004, graphene has been widely exploited and termed as a wonder material. It is a flat monolayer of carbon atoms compactly packed into a two-dimensional (2D) honeycomb network.
Physicists around the world are currently very interested in studying and investigating the physical properties of carbon nanotubes, such as their astounding strength and both their thermal and electrical conductivity.

Over the last several years scientists from the National Institute of Standards and Technology (NIST) have been studying how to make nanomotors move around when suspended in a liquid. In 2012 a team of scientists from Penn State first observed that metal nanorods would rotate in response to ultrasound, but the reason why has baffled scientists since its discovery. The research conduct by the NIST could now offer new insight and applications inside the human body.
